Description

Membrane pond water treatment system Technical Field The utility model relates to the technical field of water treatment, in particular to a membrane pool water treatment system. Background The membrane pond water treatment system is a system for purifying and treating water quality by utilizing a membrane separation technology, and is widely applied to the fields of drinking water treatment, sewage treatment, industrial wastewater treatment and the like, as disclosed in the prior art, a facultative biomembrane hydrolysis reaction pond and a wastewater treatment system are arranged in the reaction pond, the reaction pond is provided with an acetic acid inlet, a wastewater inlet, a sludge inlet, a water outlet and a sludge outlet, the reaction pond is of a multi-gallery structure, the reaction pond is divided into a plurality of galleries which are mutually communicated by gallery partition walls, and each gallery is provided with a plurality of air inlet main pipes, a plurality of air inlet branch pipes, a plurality of rotary-cut mixed flow aerators, fillers and filler brackets. Aluminum sulfate is mainly used as a coagulant in a membrane tank water treatment system, suspended matters, colloid and partial organic matters in water are removed through electric neutralization, adsorption and flocculation, the membrane filtration efficiency is improved, and the water quality of effluent is improved. The operation effect and stability of the membrane pond water treatment system can be improved by reasonably controlling the adding amount of aluminum sulfate. The traditional aluminum sulfate adding mode is usually manually controlled and added, and accurate dosage cannot be added according to the actual water quantity of each gallery in the membrane tank, so that the dosing is uneven and the water treatment effect is affected. Disclosure of utility model Aiming at the problem that the manual work can not accurately dose according to the actual water quantity of each gallery in the prior art, the utility model provides the membrane pool water treatment system, which can automatically add accurate dosing according to the actual water quantity of each gallery, reduce the medicament waste and improve the water treatment effect. In order to solve the technical problems, the technical scheme provided by the utility model is as follows: The membrane pool water treatment system comprises a membrane pool provided with a plurality of galleries, a medicament storage tank, a medicament adding pump, a medicament adding main pipeline and a plurality of branch pipelines, wherein the inlet end of the medicament adding main pipeline is communicated with the medicament storage tank, the medicament adding pump is arranged on the medicament adding main pipeline, the inlet ends of the plurality of branch pipelines are communicated with the outlet ends of the medicament adding main pipeline, the outlet ends of the plurality of branch pipelines are communicated with the galleries one by one, water inlet flow meters are arranged at the water inlet ends of the galleries, first flow regulating valves are arranged on the branch pipelines, and the system further comprises a controller. It will be appreciated that the water inlet end of the gallery may refer to the water inlet of the gallery, and may refer to the water inlet conduit to which the water inlet of the gallery is connected, through which water is distributed to the different galleries. In the technical scheme, the actual water quantity in the gallery can be determined by measuring the water inflow of the gallery. After the water inflow flow of the gallery is measured by the water inflow flowmeter, data are sent to the controller, and the controller controls the start and stop of the dosing pump and the opening of the first flow regulating valve according to the actual water amount in the gallery, so that aluminum sulfate in the medicament storage tank flows into each branch pipeline through the dosing main pipeline and finally enters different galleries. Because the opening of the first flow regulating valve on each branch pipeline is different, the aluminum sulfate amount added into each gallery is also different, so that the accurate control of the adding amount of the medicament in each gallery is realized. The controller accurately controls the aluminum sulfate adding amount of each gallery according to the actual water amount in each gallery, so that excessive or insufficient medicament is avoided, flocculation effect can be ensured, medicament waste can be avoided, and medicament cost is saved. Preferably, the branch pipelines are internally provided with medicament flow meters, and the medicament flow meters are in signal connection with the controller. The agent flowmeter can measure the actual adding amount of aluminum sulfate in each branch pipeline in real time and feed back the actually measured agent flow to the controller, and the controller dynamically adjusts the o
